JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
I have checked your form and it appears to have one hidden field but it is not associated with any conditions or any calculation. If you could give us some details regarding what you are trying to achieve we will be happy to assist you with it.
We look forward for your reply.
